17 Claims. (Cl. 93-8) This invention relates to a machine for making handles for shopping bags and for applying the same to the bags.

?More specifically the invention relates to a machine adapted to make shopping bag handles such as disclosed in the application for patent of True M. Avery, Serial Number 696,727, filed September 13, 1946; and vto apply said handles to preformed bags.

Ari-object of the-invention is to provide a machine for making handles of the type stated simultaneously in pairs, and for attaching said handles simultaneously to the opposite sides of preformed bags.

A further object-of the inventionis to provide amachine by means of which multi-ply handles may be formed from single-ply strips of material, and secured to the bags.

A further object of the invention is to provide a device as mentioned which may be readily adjusted to vary the length of the attaching portions of the handles.

Other objects will appear hereinafter.

The invention consists generally in a machine adapted to continuously crease, paste and fold a strip of paper, or other suitable material, longitudinally to form a multi-ply tape, sever said tape into sections of proper length, fold the severed sections to form handles comprising a grip portion and connecting end portions atsubstantially right angles thereto, and pasting parts of said end portions to preformed bags.

The invention further consists in a machine as above stated, adapted to form said handles simultaneously in pairs, and simultaneously attach said handles to the opposite sides of the bags.

The invention further consists in novel means for continuously pasting and folding a strip of material'longitudinally to form a .strip or tape of multi-ply thickness.

The invention further consists in a machine for continuously pasting and folding strips longitudinally to form multiply tapes, in combination with means for folding the pasted and longitudinally folded strips-to form bag handles.

The invention further consists in a machine including a strip folding mechanism as above stated, in combination with novel means for maintaining sufficient tension on the strip to avoid slack, without tending to break or tear the strip when moistened by the paste applied thereto.

The invention further consists in a machine adapted for the purposes above stated, and in :such combinations and arrangement of parts as are hereinafterdescribed andparticularlypointed out in the. claims.

The invention will .be more readily understood by reference to the accompanying drawings,

In order that the invention may be more readily understood, a brief description of the machine as a whole will be given before describing the same in detail. In this brief description no attempt is made to describe particular features of the machine and their advantages, but merely to state the principal parts and their general operation.

The handles which are made by the machine are formed from continuous strips of materal, preferably a suitable paper, which are supplied in rolls; and as the handles are made simultaneously in pairs and afiixed simultaneously to the opposite sides of the bags, separate rolls of material are provided from which the handles of each pair are made. To this end means are provided for supporting a pair of said rolls, preferably coaxially, and in a manner whereby either roll, when exhausted, may be readily replaced by a fresh roll.

From these rolls the strips of paper are drawn through a scoring device which scores each strip longitudinally along parallel lines, dividing the same into a central portion and a pair of lateral portions, the latter being preferably of slightly
